AIR'CRAFT SAFETY DEVICE original Filed April l2, 192s Patented Oct. 7, 1930 .UNITED STATES' PATE Nr OFFICE exons-E amers mns, or JAcxsoN mams, :mw You menen sum navran My invention relates to improvements in aircraft safety devices, and more particularly has reference to, and is illustrated in the accompanying drawings inits application to a parachute o r series of parachutes adapted to beconned when not -in use within the wing or aerofoil of the machine.

respectively traversed by the ribs 7. Between' these spars and adjacent the lower surface of the wing are pivotallymounted a series of flaps 8, upon which the parachute .is folded and laid. The to surface of the wing structure comprises a inged section or cover 9.`

At the free end of the cover and at points alon .the main spar are provided cylindrical l portions 10, adapted when the cover is closed to be in alignment so as to be engaged by the hooks 11, on the bar 12, provide with a ring 13, so that whenthe bai` is pulled rightwardly looking at Figs. 1 and 4, the cover 9 is released and catches the onrush of air which -throws it backwardly in a substantially vertical position, the pressure of air beneath the iiaps 8 throwing the same upwardly and shooting the parachute into the air, wherey it o ens, and being secured to the machine a ost immediately checks the descent of the same. l

Of course it will be understood that various modifications may be? made in the construction and arrangement of partswithout departing 'from the'spirit of the invention as claimed.

I claim r- 1. In combination withthe ace between the vupper andlower surfaces o an aerofoil,

- a releasable cover forming when closed a continuation of said l.upper surface, and means forming the lower surface thereof adapted to beloperated by the pressure of air thereon for eecting anything within said space.

2. combination with the s ace between 6o the upper and lower surfaces o an aerofoil,

a releasable cover forming when closed a continuation of said upper surface, a parachute within said space, and a series of flaps formin the under surface of said aerofoil'll". adapte when said cover is released to ejectA said arachute upwardly therefrom.

3.; combination with the space between the upper and lower surfaces of an aerofoil, a releasable cover forming when closed a 0 continuation of said' upper surface, a parachute within said space, and a series of flaps ,y forming the under surface of said aerofoil adapted when said cover is released to eject said parachute upwardly therefrom, said l5 cover when released adapted to remain substantially upright.

4. In combination with the space between the upper and lower surfaces of an aerofoil, a "releasable cover forming when closed a 70 continuation ofA said upper surface, and means forming the lower surface thereof adapted to be operated by the pressure of air thereon for ejecting anything within said space, said space extending fore and aft from 75 the main spar to the rear spar of said aerofoil.

5. In combination with the space between the upper and lower surfaces of a hollow body carried by a iyin'g` machine, a releasable cover forming when closed a continu- 80. ation of said upper surface, and means forml, ing the lower surface thereof adapted to be operated by the pressure' of ai-r thereon'for ejecting anything within'said space.

6. In combination with the space between the upper and lower surfaces of an aerofoil said space extending fore and aftfrom the main spar to the rear spar thereof, a releasable cover forming when closed a continuation of said upper surface, and means D'.

forming the lower surface thereof adapted v to be operated by the pressure of air thereon for ejecting anything within said space.

7. In combination with the space between the upper and lower surfaces of an aerofoil, a releasable cover forming when closed a continuation of said upper surface both of said surfaces being curved and substantially parallel, and means forming the lower surface thereof adapted to be operated bythe pressure of air thereon for ejecting anything within said space.

8. In combination with the space between the upper and lower surfaces of the top aerofoil of a iiying machine, a releasable cover forming a continuation of said upper surface, and means forming the lower surlface thereof adapted to be operated by the pressure of air thereon for ejecting anythin within said space.

9.gIn combinationr with a substantially rectangular space between the upper and lower surfacesl of an aerofoil,l a releasable cover forming when closed a continuation of said upper surface, and means forming the lower surface thereof adapted to be operated by the pressure of air thereon for ejecting anything'I within said space.

10. In combination` with the 'space 'between the upper and lower surfaces of an aerofoil having an indented portion, a releasable cover yforming when closed a conltinuation of said upper surface, and means formingl the lower surface thereof adapted g5 to be operated by the pressure of air thereon for ejecting anything within said space.

11. In combination with the space between the'upper and lower surfaces of an aerofoil, a releasable cover forming when closed a continuation of said vupper surface, and means forming the' lower surface thereof and comprising a series of substantially parallel and rectangular naps adapted to be operated by the pressure of air thereon for ejecting anything within-said space.

12. In combination with the s ace between the upper and lower surfaces o an aerofoil, a releasable cover forming when closed a continuation of saidv upper surface, and means forming the lower surface thereof and comprisin a plurality `of valves sub stantiall in t e same plane ada ted to be operate by the pressure of air t ereon for e]ecting anything withiny said space.

13. In combination ,with the s ace between the upper and lowersurfacesb an aerofoil, a. releasable cover forming when closed va continuation of said upper surface, a parachute within said space, and a series of arallel flaps substantially-in. -the same' p ane forming the under surface of said aerofoil adapted when said cover is `released to eject said parachute upwardly-therefrom.

.-14. In combination with the the upper and lower surface o an 'aerofoi1,

lace between a releasable cover forming when closed a In testimony whereof I hereunto affix my signature.
